Jennifer Lopez went without underwear and sizzled in a nude gown at the 2015 Billboard Music Awards. Lopez looked better than ever flaunting her underboob, reverse cleavage and 10-pound vegan diet weight loss.

Jennifer Lopez is no longer 100 percent vegan, but sticks to a mostly vegan diet because it has motivated her to eat more vegetables. JLo’s foray into veganism was inspired by the 22-day vegan diet challenge Beyonce and Jay-Z undertook in December 2013.

The 22-day vegan cleanse was designed by Beyonce’s trainer, exercise physiologist Marco Borges, creator of the 22 Days vegan protein bars, which Beyonce is a huge fan of.

While low-carb diets such as the Paleo, Atkins and ketogenic plans are all the rage these days, Borges said a high-carb vegan diet is better for weight loss and overall health.

Marco advocates a vegan diet that eliminates dairy and all animal products with an 80-10-10 macronutrient ratio. Borges says 80% of your diet should be carbs (from plant-based foods), 10% should be protein, and the remaining 10% should be fats.

Beyonce credited Marco Borges’ vegan diet for her 65-pound weight loss. Bey is also a fan of Marco’s 22 Days nutrition bars.

Borges, who shares his vegan diet and weight loss tips in his bestselling book, The 22-Day Revolution, said his high-carb vegan meal plan helped Beyonce lose 65 pounds several months after she gave birth to daughter Blue Ivy in 2012.

The 5-foot-7 Beyonce, who once weighed 195 pounds, lost 65 pounds using Marcos’ vegan diet plan, and said it can do the same for you.

Beyonce has since maintained her weight loss and recently made jaws drop after flaunting her unbelievable body in a nude Givenchy gown at the 2015 Met Gala (see photos above).

According to Borges, CEO of 22 Day Nutrition protein bars, following an 80-10-10 diet will promote effortless weight loss and dramatically improve your energy.

“With most diets, you see weight loss and then as soon as the program ends the weight slowly starts to add back up again,” said Borges. “With ‘The 22-Day Revolution, you’ll experience weight loss, improved sleep, clear skin, increased energy, improved sex drive and more.”
